Apple rolled out iOS 17.4.1 approximately three weeks ago on March 21, following the release of iOS 17.4 by more than two weeks. While the previous update introduced new features such as enhanced Stolen Device Protection options and Podcast transcripts, iOS 17.4.1 primarily focuses on patching zero-day vulnerabilities that could be exploited by malicious actors. Zero-day vulnerabilities are security flaws that can be leveraged to gain access to vulnerable systems in software or hardware, as defined by IBM.
To install the update, navigate to Settings > General > Software Update, select Update Now, and follow the prompts displayed on-screen. “This update delivers essential bug fixes and security enhancements and is highly recommended for all users,” Apple stated in the update’s description.
According to the update’s CVE entry (common vulnerabilities and exposures), iOS 17.4.1 addresses two issues that could potentially lead to arbitrary code execution. Arbitrary code execution, as explained by the IT services company Okta, could enable third parties to steal data or compromise devices for malicious purposes. While Apple did not confirm active exploitation of these issues, they acknowledged the potential risk if left unaddressed.
Apple credited Google’s Project Zero, a team of security analysts specializing in identifying and reporting zero-day vulnerabilities in software and hardware, for discovering both issues.
